Grapefruit is a tropical citrus fruit that is high in vitamin C. It comes in a white or pink variety and can range from bitter to sweet. Like all fresh produce, grapefruit is perishable and should be stored properly for optimum safety, but how you store it depends on whether it is whole or peeled. Peeled grapefruit will not last as long as whole grapefruit, so for best results, peel your grapefruit when you are ready to eat it. Peel the skin of grapefruit and the white membrane that surrounds the fruit with a sharp knife or your fingers.
Slice off each end of the grapefruit using a sharp knife.
Stand the grapefruit up on one of the ends to make it easier to peel. Insert the tip of the knife in between the peel and the flesh of the grapefruit on the top end and loosen the peel.
Continue peeling the skin of the grapefruit with your fingers.
Cut into the grapefruit peel, without cutting into the edible flesh of the fruit, with a sharp knife at one end of the grapefruit.
Slice the peel using a sawing motion starting at the top.
Make your way around the grapefruit in a spiral fashion to cut away the entire peel.
Leave the grapefruit fully intact and store it at room temperature, in a cool, dry place. Grapefruit can typically be stored this way for several days, but watch out for bruises or spoil spots on the skin of the grapefruit.
Store fresh whole grapefruit in the refrigerator, either in a plastic bag or the produce drawer, for best results and the longest storage time, up to three weeks.
Place cut grapefruit into a tightly sealed food-storage container or food-storage bag and store it in the refrigerator for up to five days. For best results, wrap the cut portions of grapefruit with plastic wrap to help keep as much air out as possible so that the grapefruit does not become dry.
Store the juice or grated peel from the grapefruit in the freezer for later use.
Do not store whole grapefruit in the freezer.
Do not eat the grapefruit if the skin grows mold or the fruit begins to emit a bad smell.
